Measurement of the Ξ0 → Λγ decay asymmetry and branching fraction

Measurement of the Ξ0 → Λγ decay asymmetry and branching fraction

In data taken with the NA48 experiment at the CERN SPS in 1999, 730 candidates of the weak radiative hyperon decay Ξ0→Λγ have been found with an estimated background of 58±8 events. From these events the Ξ0→Λγ decay asymmetry has been determined to α(Ξ0→Λγ)=-0.78±0.18stat±0.06 syst, which is the fir...
